WIND OW GUARD.

Application filed. March 23, 1922. Serial No. 546,152.

To allwhom 1f/may concern: Y

Be it known that I, A Nenno JosLnR, a citizen of the VUnited States, and a resident of Chicago, Cook C'ounty, and State of Illinois, have invented certain new and useful Improvements in Window Guards, of which the following is declared to be a full, clear, and exact description.

This invention relates to window guards and its principal Objectis to provide a sim-V ple, practical and highly efficient window guard of novel and improved. construction, which may be readily installed, is automatically locked whenever the sash is raised, and which is adjustable to accommodate itself to windows of various widths. another object is to provide awindow guard which may be swung open when the window sash is in its closed position and which may be 'quickly detached from .its supports and removed from the window. Another object is to provide a swinging window guard with locking means controlled by the sash, and arranged to keep 'the guard in locked position while the sash is raised above its closed position.

Another object is to provide supplemental guard locking means, under the control of the sash, which supplemental locking means may also be employed to secure the guard in placewhen the sash is in its lowered or closed position.VV Another object is to pro vide a window guard'which 'is attractive in appearance, is ornamental and is of substantial construction, whereby the window is pi'oteoted'against the entrance of ,unauthorized persons, and which acts as a safeguard to prevent-childrenor other persons from, fallingout of the window. Other objects and advantages will occur in the course of this specification, and with all of said objects and advantages in view, this invention Consists in the several features of construction,@arrangement and combination of parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the drawings accompanying this specification,

in which, Fig. 1 is aside elevation, partly` broken out, of a window guard embodying one form of the present invention; Fig. 2 is a'horizontal section taken on the line 2-2 of Fig. 1; Fig. 3 is a view similar' to Fig. 2 but showing the window guard in a partly open position; Fig, e is an edge View of one member of the guard looking in the direction of the arrow 4; in Fig. 1; Fig. 5 is a detail horizontal section taken on the line 5-5 of Fig. 1; Fig. 6 is a detail horizontal section taken on the line 6-6 of Fig. 1; Fig. 7 is a View partly in front elevation, and partly in vertical section, showing a slightly modified form of supplemental locking mechanism; Fig. 8 is a plan of the parts seen in Fig. 7; Fig. 9 is a side elevation of a second modified form of supplemental locking mechanism; Fig. 10 is a side elevation illustrating a modified form of the invention and Fig. 11 is a horizontal section taken on the line 11-11 of Fig. 10.

Referring to said drawings, and irst to Figs. l to 6, inclusive, the reference characters 12, 12, designate the upright frame members of a window casing, 13 designates the sill and 14 the lower sash of a window, which parts are constructed in accordance with the common and well known type of sliding` windows. Secured to the inner faces of the upright window casing members 12, in front of the lower sash, are two companion guard supporting brackets 15, which, for convenience, may comprise bars of metal having transversely bent end portions 16 which form ears or lugs that support the window guard proper. Said brackets are secured to the upright members 12 of the window casing by screws 17.

The window guard proper comprises a pair of window guard members 18, 18, which are removably, and pivotally or hingedly secured upon the brackets 15, whereby they may be swung into closed position, as illus trated in Figs. 1 and 2, or may be swung into open position, and may be removed from the supporting brackets 15 only when in said fully open position. The two window guard members 18 are substantially alike,.in construction, except that one is a right hand guard member and `one isa left hand guard member, and one is provided with a certain joint covering member, and with a supplemental locking member, as will be hereinafter set forth.

Generally speaking, each window guard member 18 comprises three frame members 19, 20, 21, and a horizontal brace bar 19a, rigidly secured together, as for instance by spot-welding them together, and an upright frame member 22 which is adjustably connected to the frame members 19, 20, by horizontal rods or bars 23, that are `slidably mounted in upright portions 24,25, ot the frame members 19, 20. Set screws 26 threaded in the upright members 24 bear against certain ofthe rods 23 and hold the parts in adjusted position. The free ends or the rods 23 may be provided with knobs or other ornamental objects 27, to give a inished appearance and also to prevent the rods 23 :from being drawn out of the upright frame members 25. The opposite ends oit" the rods '23 may be threadedly secured in the upright frame members 22 and'their outer ends are headed down upon the outer sides of the upright frame mcmbers^22, as at 23, so as to4 render it diliicult to disconnect the rods .23 from said upright framezmembers 22.

Obviously, the rods 23 may bepermanently secured to theupright frame members 22 by other well known methods, for instance, they may be spot-welded thereto. Each upright member 25 is plL ced intermediate the upright member 24 and-associated frame member 21,l and bothfra-me' members 19, 20, are formed with horizontally extending portionsz29, 30,'which extend'to and'rest upon the ears 16 of the brackets 15. The upright frame members 21 are illustrated in the form otround rods, and their-upper ends are formed` with' U bends 31, the end portions 32 oi? whiehproject down and-enter keyhole slots 32 (seefFig. 5) in the upper ears 16 of the brackets 15. The lower ends oft the frame-members 21 are formed with reverse bends 33 which terminate in downwardly projecting portions 34 that pass .through keyhole slots 35 '(see Fig. 6) in the Vlower ears 16 of the brackets 15. Said end portions 32,134, of frame members 21,oim pintles or pivot pinswhich turn in the apertures or keyhole slots 32, 35,01z the ears, 16. and short pins 36, 37, are secured in the pintles 32, 34, below the ears 16, and are arranged to engage with the undersides of saidears to prevent the `window guard-members 18 from being raised when in closed position. vWhen swung into fully open position, the window guard'members Vmay be detached from the brackets, because in this position the pins 36, 37, stand in alignment-with the parts 38 of the keyhole slots 32', 35. It

shouldbe noticed that the lateral parts 38 of the upper keyhole slots 32 project toward the upright members of thewindow casing Aand that the lateral parts 38.01E the lower keyhole slots 35 project away from the up- 'rightmembers ofI the window casing. This arrangement permits the pintles or pivot pins to bear laterally against the round or unbroken surfaces of the keyhole slots 32` 35,5inasmueh:asA the weight offthefguard member is to one: side of the pivot and the tendency is to draw the upper pintle in a direction away from the casing and to force the lower one toward it..

The upright 'frame members 22 are arranged to be interlocked with a guardlocking member 40, which .is secured to the lower horizontal member 14a of the sash`14 by screws 49. The parts are such, however, that when the sash is fully closed,'both window guard members V18 may be swung into open position. This interlocking arrangement is provided byv twoupright lock bars 41, which, in the form of the invention illustrated, are in the form of iiangcsI formed upon the `upright frameA members 22 and vco-operate `with flangeholding` members or shoulders-i5() that are iformed vupon' the locking member 140 andoverlap the langes4l.V The lianges41 stop short of .the Aloekingmember 40'when the `sash is closed, `but are ibrought; into` locklower sash israisefl above its' closed position.

ing engagement therewith' `whenever the Conveniently,.the .upright'framemem'bers 22 may comprise angle'iron bars (seedig. 2) and to one of said upright frame. members 22 is rigidly secured an angle iron bar44whi'ch4 covers the gap Vbetween `the Vtwo upright frame 'members 22, when theitwo guard members 13 are closed. The fends ,of the horizontal rods 23 of' oneguardmember'pass through the contiguous webs of the ,frame member 22 and angle iron'bar44xand the rods 23 lof the otherguardfmember 18 .pass through a1re-enforcingistrip44? and through the Vcontiguous Aweb of the associated'v angle iron bar A22. The anglei iron bars;22,- 44,?may be spot-welded togetheratseveral places,

,and the angle iron bar 22 and*strip-'44a may be spot-welded together Vat'several placesso as to permanently connect theseparts vtogether. Y

The locking memberV llO'may: bel formed of bars or strips of metal bent up intov the form shown in Figs. 2 and 3, and as aconvenie-nce, said locking i member may comprise a dat basestrip 46, two bent up Z members, 47, 47, secured thereto, and a bent Vup brace-member 4-3wliich is secured to the base member 46 and to the side portions'of the Z members between theopposingledges otr-parts orsheulders providesavslot forftherreception of web portions `of the uprightframe membtrs2.V The flangesf4lof the upright 'frame me1nbers22 stand between the shoulders 50 and the Vbracemember4.8v andere adapted Vto enga-gefrwith said shoulders and brace memberin: case the window guard? is swung outward or inwardfwllel ills-Sash is raised..

At the upper ends of the upright frame members 22 are secured two pieces or strips of metal 51 which extend into the path of movement of the shoulders 50 of the locking member 40, and form abutments or stops limiting the upward movement of the locking member, thus preventing it from being withdrawn fromthe upper ends of the frame members 22.

For the purpose of securingthe guard members 18 in closed position' while the win dow is closed, and also to provideY supplemental locking mechanism for the guard members when the window is open, I provide a locking bar 52 which Vis rigidly secured upon the pin or rod 53 that extends through the front flange of the angle iron bar 44 and through a bracket 54 secured to the" frame member 22, and said locking bar 52 is arranged to engage with hook-like keepers 55 riveted or otherwise permanently fastened to the upright members 24, 22, of the gua-rd members.

The inner end of the pin Vor rod 53 has an arm 56 secured to it or formed as a part of it, which` when the lockingb-ar 52 is in engagement with the hookdike -members 55,

extends upward in a vertical direction from the pin or rod 53. and stands between two rod engaging members 48a which are formed on thebrace 48. As a consequence, the locking bar V52 is positively kept in engagement with the hook-like members 55 whenever the lower sash is raised sufficiently to bring the brace 48 of the lockingmember 40 into eiective engagement with the arm 56 ot the locking bar 52. pin 57 secured in the angle iron bar 44 provides a stop for the looking bar 52 when-tilted and holds it in i its unlocked position.

When the guard members 18 are swung into closed position, as 4indicated in Figs. 1 and 2. they become locked inlsuch position as soonas the sash is raised above its closed position, because the brace 48 and shoulders 50 of thelocking member 40 then overlap the'upright flanges 41 of the guard members and prevent the guard members from being moved inward or outward from their closed position. Whenever the sash is raised high enough to brine' the locking member 40 into engagement with the rod4 56 of the locking bar 52. the latter is effectively held in engagement with the keepers 55, and the guard members are thereby further secured against any ordinary forceV directed against them.

` IVhen the sash is fully closed. the guard members are automatically disconnected from the locking member 40. and by swinging the locking bar 52 upon its fulcrum and disconnecting it from its keepers 55, the .fruardmembers in ay be swung into the room. In this position they may be detached from v Vthe supporting brackets 15 bylifting them up and drawing the pintles 32, 34 and pins 36, 37, through the keyhole slots 32', 35. t will be noticed that the screws which secure the supporting brackets 15 to the window casing and some of the screws which secure the locking member 40 to the sash are covered by other parts when the guard members are in place, thereby making it xtremely diiiicult for an unauthorized person to remove the screws and detach the guard.

In the form illustrated in Figs. 7 and 8, the supplemental locking member is shown as comprising an arm 56L pivotally mounted upon one upright frame member 22a and having a locking lug 52a which passes through a hole in the companion upright frame member 22a. The locking bar 56a is arranged to stand between the sides of the locking member 40a whenever the lower sash is raised sufficiently to bring the locking member 40a up to the bar 56a.

In Fig. 9, the arm 56 is shown as provided with a downward extension 561. This arrangement provides means whereby the locking member 40 will become etl'ective in holding the supplemental locking members in locked position, whenever the sash is raised above its closed position. The exten sion 56b may extend down to within a short distance of the locking member 40, if so desired, or it may be made shorter if desired.

In the form illustrated in Figs. and 11, the guard members 18c are shown in the form'of the common and well known collapsible gates or guards. They may be hinged to the brackets by ears 82C, which are secured to the end frame members 21C, and their other frame members 22c are preferably formed in the same manner as those of the preferred form and are arranged to interlock with the locking member c secured to'the sash 14. In this form, the supplemental locking member may be dispensed with, if so desired. The guard members may be collapsed laterally to leave a free space, or they may be swung into the room, as is well understood. When swung into the closed position illustrated in Figs. 10 and 11, the end frame members 22c and locking member 40c become interlooked whenever the sash is raised from its closed position.

It is understood that when the window guard forming the subject matter of this specification is employed infront of the lower sash of a window.V a latch or bolt of some sort is provided Jfor the upper sash to prevent it from being lowered, and in case the guard is provided for the upper sash, the lower one is provided with a latch or bolt.
